A three component model for hadron $p_{\mathrm{T}}$-spectra in pp and Pb-Pb collisions at the LHC

Abstract

A three component model, consisting of the hydrodynamical blast-wave term and two power-law terms, is proposed for an improved fitting of the hadron spectra measured at midrapidity and for arbitrary transverse momenta ($p_{\text{T}}$) in pp and heavy-ion collisions of different centralities at the LHC. The model describes well the available experimental data for all considered particles from pions to charmonia in pp at $\sqrt{s}=$ 2.76, 5.02, 7, 8 and 13 TeV and in Pb-Pb at $\sqrt{s_{\mathrm{NN}}}=$ 2.76 and 5.02 TeV.
